I've been off X for the last 4 months. How is it going?

In that time, we opened 2 new markets for Persikas, including Estonia and Finland

And in general, 3x the whole business.

Will be sharing some updates more often on what worked with Persikas

Anyone generating real money with this?

I just tried Kling AI with motion capture, but I can't get such great results. I need some tutorials 😂

[Modestas Jurčius @MJurcius]

@said_azizow I've seen a few as well but much less than last year and year before during January time

[Modestas Jurčius @MJurcius]

Is it just me, or has starting to go to the gym in January stopped being a trend?

It’s completely empty here

[Modestas Jurčius @MJurcius]

@JesusAnutrof 💪💪💪

[Modestas Jurčius @MJurcius]

@Elans_x Yeah that's weird :D Well less competition I guess

[Modestas Jurčius @MJurcius]

Good morning hustlers

This weeks goal is to decide which market we will go to next with Persikas

We are thinking 🇫🇮

Good morning hustlers

I looked through other creators and I became a bit jealous of people who wake up earlier. So today I woke up already at 9 am instead of 10

Pushups done ✅

[Modestas Jurčius @MJurcius]

Are we cooking?

[Modestas Jurčius @MJurcius]

Good morning builders

Time to conquer new markets!

Pushups done ☑️

That just made my day hearing this! 🫶

@MJurcius Impressive year. I know a few people who are using your app and they are happy with the results. All the best in 2026!

[Modestas Jurčius @MJurcius]

@nerijusoftas Thank you man!

Yearly review of https://t.co/ftC4v1ffGr from the product side 🎉 🚀

- Onboarded more than 25,000 users to our app in Lithuania.
- Remained the #1 Health & Fitness app in Lithuania on both the App Store and Google Play.
- Added many new features based on user requests.
- Implemented agentic features and made nearly all API endpoints available to AI for plan modifications.
- Kept the tech team the same size.
- No full-time developers were fired or left the team 🙏.
- Made the app multilingual: English, Lithuanian, Latvian, and Estonian.
- Fixed hundreds of bugs.
- Conducted around 50 live user calls to guide the product roadmap.
- Achieved 99.98% uptime (t3.small instance carried the entire product).
- All bugs and errors are reported, monitored, and investigated almost instantly across three Slack channels.

Another challenging year for Persikas. We focused on UX improvements and reliability, added extensive monitoring throughout the app and servers to prevent crashes from avoidable mistakes, and finally rewrote the app for multilingual support by year-end. This positions us to enter 2026 ready to expand across Europe.

I’m truly proud of every dev team member for their dedication, commitment, and extra effort - even on weekends - to build an app we can all be proud of! 🫡

The new upgraded instance is just chilling with the new traffic that we are getting

You need to be on attack mode in life

[Modestas Jurčius @MJurcius]

We are number 1

[Modestas Jurčius @MJurcius]

2 cores and 2 GB of RAM ran the majority of our backend at https://t.co/ftC4v1ffGr.

Over €1M generated and 35k users served on a single instance with an average of 99.91% uptime.

You can go quite far with a t3.small instance in AWS, as long as you keep your code clean and optimized both in the back and front ends!

Today, I shut it down and replaced it with a new monolith instance 8x larger for better scale and reliability.

Does anyone know some native Estonian speakers who would proofread and fix GPT-translated recipes?
